dynaudio bm6a vs bm15a

I own a pair of Mackie HR824s and after being part of that recent huge thread on the Mackies that went on forever, I've decided to sell them and buy a pair of Dynaudio's.

Does anyone have any opinions on the BM6A vs BM15A ?

I'm talking about accuracy in the low end and overall sonic quality, etc, as was discussed in the above mentioned thread.
